there is a recall on the 2021 cadillac xt4, fuel pump control module, N252516900, but my vin is not included. My vehicle seems to be having the same issue. The dealer has been unable to diagnose as it has been happening very sporadic and I don't drive often. Issue first occurred, vehicle would not start in June 2025, clicking noise, happened few times in December and now seems to occur more frequent. car will initially start but will stall and fail to start. vehicle usually starts and engine light stays on, but then engine light will go off within hours. Dealer indicated no error codes were stored. had onstar run a diagnostic today when I had issues and identified a fuel management system is

Driving down the highway yesterday, I believe that the sunroof on my Cadillac XT4 exploded. It was a hot day and I heard a loud bang. My sunroof shattered and no rocks or other external debris to be found.
